So I decided to finally fixed the burnt out bulb in my Tascam M-3700's VU meters. I happened to have some nice white LEDs from some dead solar lights and thought that would be a nice change from the aged yellow of the tube bulbs that were in there. Dropped a 1k resistor in front and everything meters out fine. However, the meter that had the burnt out bulb still doesn't light up. I double checked the bulb itself and it is in fact popped. Quadruple checked everything on the PCB and everything is good. It lights up when I put the diode setting on my MM to it from various locations on the board but still no light when I plug in the PCB. Popped the hood on the master section of the board itself and checked all the connects are good and seated to no avail.
Ideas?
